CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 430,917, dated June 24,1890.

Application led April 29, 1890. Serial No. 349,895. (No model.)

To all whom it may concern:

Be it known that I, CHARLES JAsoN BUM- PUS, a citizen of the UnitedStates, residing at Fayette Station, in the county ofl Fayette and Stateot' IVest Virginia, have' invented certain new and useful Improvementsin Car- Oouplings; and I do declare the following to be afull, clear,and exact description of the invention, such as Will enable othersskilled in the art to which it appertains to make and use the saine,reference being had to the accompanying drawings, and to the letters ofreference marked thereon, Which form a part of this specification.

This invention relates to car-couplin gs, and particularly to draw headsand bars.

The object of the invention is to provide cars with draw-heads whichwill at all times when the cars are coupled together have an even anduniform bearing on each other, no matter how uneven the tracks or whatform of curve occurs in the track over which the cars travel.

A further object of the invention is to provide a draw-head which, Whencoupled to another like draw-head, will have a sufiicient amount ofbearing against each other to great-ly assist in preventing the lswayingand disagreeable jumping, and also by this uni.- form bearing of onehead into another the danger of cars being becoming derailed is muchobviated.

The invention consists in forming a double draw-head on a singledraW-bar-that is, I out out my draw-head in such a manner as to form apin-hole on either side of the centraiA line of the draw-bar.

The invention also consists in forming the face of a draw-head withsymmetrical curves, with the pin-holes located at the same angle as suchcurves, as Will be hereinafter more fully described, and set out in theclaims.

In the accompanyingdrawings,foiming part of this application, Figure lisa top plan view of my dravv` head and bar in position to be coupled.Fig. 2 is a similar view showing the draw-heads coupled. Fig. 3 is afront elevation of my improved draw-head with 011e of the coupling-linksin place.

Like letters of reference denote like parts throughout the figures.

A denotes the draw-bar of any ordinary construction, but must havesufficient metal at the end to form the draw-head B, although the head Bmay be formed of a separate piece and bolted or otherwise securelyattached to the draw-bar A, which is formed with one side C more thantwice as thick as the opposite side D. The face E of the draw-head B isformed by a symmetrical compound curve made at an angle of aboutforty-live degrees from the draw-bar, which leaves the face E to presentfrom top view an S-shaped head. By forming the draw-head S-shaped theportion O has a convex surface-bearing c, and the portion D has aconcave surface-bearing d. The portion C is provided near its face witha coupling-pin hole F, adapted to receive an ordinary coupling-pin f,and on a line with the S-shaped curve, at an angle of forty-tive degreesnear the face d of the concave portion D, is located a like hole G. Theportion D is extended horizontally as far as the face c of said portionD, and the end g of said portion D rounded so that the draw-heads whenbeing coupled Will be more certain to move into their proper position,as shown in Fig. 2. The main or central portion of the concavebearing-surface CZ is cut out to form an enlarged openingr for thecoupling-link H'. The top and bottom of this cut-out has a curvedsurface 7L and h', respectively, so that the coupling-link may have aclear and free entrance. In the face c of the convex portion O is formedthe link-seat I by casting therein or cutting out a sufficient amount ofmetal to allow the coupling-link to tit into each space or seat I soclosely that the coupling-pin will have no play in any direction. It isintended that the link shall't into its seat so rigidly that theconnection between the draw-head B and the link H will be equally,

as firm as though they were cast together.

By constructing draw-heads With the S- shaped bearing-surface, as shown,and also each head With the extension G, which laps over the outside ofthe portion O of the adjoining head, there is little or no danger of theheads, and therefore the cars, becoming separated by the loss of ordisplacement of one of the coupling-pins; and should the IOOcoupling-pin on the same side of both heads become broken or displacedthe couplinglink Will still remain in its place as long as thecoupling-pins on the opposite side keep in proper position. Thus it willbe observed that it Would be impossible for the drawheads after beingcoupled to sway or become uncoupled by any ordinary movement of thecars, for the extension is constructed with sufficient strength toobviate such danger.

In coupling and uncoupling cars by means of my draw-head one pin fromeach head is to be removed, leaving a coupling-link firmly' secured inits seat of both heads. It has been found that this arrangementmaterially assists the draw-heads to assume their proper Y place.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In combination With a carcoupling, the draw-head having an S-shapedbearing surface or face, such face having an enlarged opening for thereception of the couplinglink of a separate draw-head, said surface orface also having a link-seat formed therein,

substantially as shown and described, and for the purpose set forth.

2. The draw-head having a convex bearingsurface c provided with thecoupling-link seat I, in combination with the concave bearing-surfaceCZ, having an enlarged opening and an extension g, substantially asshown and described, and for the purpose set forth.

3. In combination With a car-coupling, a draw-head having` an S-shapedface, and provided With coupling-pin holes on the same angle with thesaid face, one portion of which face being provided With a coupling-linkseat and coupling-pin, whereby said link is rigidly secured in the saidseat, substantially as shown and described, and for the purpose setforth.

In testimony whereof I aiiix my signature in presence of two Witnesses.

CHARLES JASON BUMPUS.
